The current prices at any given time, how do you know if they are going to correct or are already corrected?
Like the prices atm.
This is the work of Technical Analysis, to know the possible trend or the next price range of a specific coins/tokens. Indicators can be use to tell if its going to up or down, either overbought or already oversold. In TA you must consider everything, one indicator that can be backed-up by other indicators, this can be more effective.
